The Effect of Acacia mangium Leaf Feed on Apparent Metabolizable Energy, Growth Performance, and Carcass Composition of Broiler Chickens

Abstract

The experiments were conducted to determine the apparent metabolizable energy of Acacia mangium leaf meal (AMLM) and the effect on growth performance and carcass composition of broiler chickens (Arbor acres). Twenty-four broiler chickens at the age of 24 days were divided into 2 groups with four replications of two chickens raised individually in a cage. The apparent metabolizable energy of AMLM-feeding chicken was 2,359.90 kcal/kg. Experimental diets consisted of AMLM 0%, 2.5%, 5%, 7.5%, and 10% feeding for 161 one-day-old unsexed broiler chickens and were randomly assigned to five groups with four replications of eight chickens in a completely randomized design. Feed and water were offered ad-libitum throughout the experimental period. At the age of 45 days, 2 broilers per replicate were slaughtered, and the carcass was determined. The results indicated that broiler chickens fed AMLM diets were not significantly different in weight gain, average daily gain and feed intake compared to the control diet (P>0.05). But chickens fed AMLM had decreased feed conversion ratio than the control (P<0.05). In addition, broiler chickens fed AMLM diets were not significantly different in all carcass composition parameters compared to the control diet (P>0.05). It is concluded that the AMLM contained 10% in diets does not affect broiler chickens' growth performance and carcass composition.

Evaluation of Nutrient Digestibility and Metabolizable Energy of Yeast-Fermented Acacia mangium Leaf by Japanese Quails

“…The waste, such as residual wood, branches/twigs, leaves, and bark, accounts for more than 60 % of the total biomass [8]. Acacia mangium leaves contain 14% CP, 2.15 % EE, 39.81 NFE, and 26.4 % CF [9], which can be used for ruminant animals [10,11]. It's possible to support broiler growth, optimum inclusion levels of Acacia mangium leaf meal (AMLM) in support growth without adverse effects on growth performance have been established at 5% in starter chicks and 10% in grower-finisher chicks [12].…”

The utilization of AMLM in poultry diets must be limited due to its high fiber content and anti-nutritional factors.…”
